Redesign on the Stitch reference, in Plus Jakarta Sans

Four passes, and the shape they landed on.

The type face is Plus Jakarta Sans (variable, wght 200-800), which brings a
fix with it: it carries the rupee glyph and Switzer does not, so prices stop
being set in Geist Mono to work around a missing character. Mono stays where
it is earned - references and phone numbers, read digit by digit.

Surfaces lift rather than outline. Cards carry two very soft shadow layers
instead of a hairline, because eight outlined boxes down a screen read as a
wireframe. The tab bar floats as a pill again for the same reason it was
right to: it is now the same kind of object as everything above it.

Screens:

* Home is the greeting, the address, the sphere and one card. The card lost
  its progress bar - a filling line says "wait", and a parcel two days into
  a journey is not something anyone is waiting through - and gained the size
  that buys.
* Orders cards are four bands: identity, destination, route, and whatever is
  happening right now. Plus a search field, because the list is the archive.
* Tracking leads with the state at display size, then TRIP MILESTONES with a
  step counter, then the courier.
* Review is a route thread over two particular cards.
* Account opens on the person: avatar, name, and two counted figures.

Three real bugs the redesign surfaced:

* Quick dispatch handed `loadCities()` straight to a FutureBuilder, so the
  catalogue was refetched on every rebuild and Home never settled.
* Order cards showed the whole visit's weight on one destination's row -
  somebody else's parcel. Per group now, and only once actually weighed.
* The pickup window was printed beside "In transit", where it reads as a
  delivery time nobody promised.

Nothing invented. The reference shows EXPRESS PRIORITY, CARBON OFFSET,
CONCIERGE ELITE and hub-to-hub routing; this backend sends none of them, so
they are absent rather than mocked up.

flutter analyze: clean. flutter test: 88 passing.
